Abstract

The invention relates to a process for obtaining hollow bodies made of aluminum alloy having a high bursting strength, and to the products thus obtained. The alloy contains (by weight): from 7.6 to 9.5% of Zn from 1 to 1.8% of Cu from 2.4 to 3.5% of Mg from 0.07 to 0.17% of Cr from 0.15 to 0.25% of Mn from 0.08 to 0.14% of Zr less than 0.2% of Fe, 0.15% of Si 0.10% of Ti and optionally less than 0.01% of V. It has a tensile stress (lengthwise direction) and a bursting strength (transverse direction) greater than or equal to 660 MPa. Its structure is characterized by the absence of large intermetallic compounds (>35 mu m) after a specific solidification test. It can be used in all the safety applications involving a container under pressure (bottles of compressed gas, etc.).
